Aug 06, 2015. Disease resistance is top of mind for many western Canadian growers. A major component of the CPS breeding program and the Proven Performance Trials is the development and rigorous testing of canola hybrids that provide growers with their required disease protection package.
The Proven Seed team, along with the entire canola industry, is closely watching the spread of clubroot. This potentially devastating, soil-borne disease causes swelling, or galls, to form on canola roots, killing the plant. Starting in central Alberta, clubroot has now been found in southern Alberta, Saskatchewan, Manitoba and North Dakota. Fields in the Edmonton area have been particularly affected. Growers in these areas should be sure to mitigate the risk by managing rotations and cleaning and disinfesting equipment that may be contaminated with clubroot spores. The next step is to choose a good canola hybrid with strong genetic resistance.
Ryan Adams, Manager of Agronomic Services (MAS) in the Edmonton region says “the dry weather has the potential to impact yields this year, but meanwhile the canola fields in this year’s Proven Performance Trials are experiencing less disease pressure than in typical years. This is particularly true for Clubroot, which is a water mobile spore.”
“We have trials in known Clubroot fields and even the more susceptible checks are not showing significant disease symptoms this year,” says Twyla Jones, MAS for North Central Alberta.
The Proven Performance Trials will be one of the first ways we test the next generation of genetics on a field-scale basis. Our research and development team has developed multi-genic hybrids with a high level of resistance to clubroot 5X pathotype, as well as pathotypes 2, 3, 5, 6 and 8. These advanced Brassica napus canola hybrids will mark a first in the fight against the growing threat of the disease.View More Proven Weekly Posts
